' cnozn.

To all whom it may concern Be it known that I Giionen SoHNnoK, a citizen of the United itates, residing at Oil City, in the county of Venango and State 01 Pennsylvania, have invented certain new and usefullmprovements in Crozes; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a coopers croze, such as employed for cutting the grooves in the staves of a barrel, short distances inwardly from the ends of the barrel, after the staves have been assembled in barrel formation, and the primary object of the invention is to provide a croze as specified which includes a main supporting body or board shaped to fit over the top of a portion of a barrel which body board adjustably carries a tool head, and to provide means for adjusting the position of said tool head with the respect to the body board, for regulating the distance from the upper edge of the barrel staves, that the groove is out.

A further object of this invention is to provide a tool head which carries a plurality of blades, and to provide means whereby the position of said blades with the respect to the head may be regulated to regulate the cutting depth of the cutting tool.

71th the foregoing and other objects in view, this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views and in which:

Figure 1 is a top plan of the croze,

Fig. 2 is a side elevation of the croze,

Fig. 3 is a vertical section on the line 33 of Fig. 2,

Fig. 4 is a detail cross section through the tool head,

Fig. 5 is a horizontal section through the tool. head, and

Fig. 6 is a section on the line 66 of Fig. 5.

Referring more particularly to the drawing, 1 indicates the main body board of the croze which is preferably constructed of Specification of Letters Patent.

wood and has its outer or long edge convexly cut as in dicated at 2 {LIlCl'llTS inner relatively short edge concavely cut as lndlcated at 3. The edges 2 and 3 are concentric.

The" body 1 of thecroze is provided with an elongated opening a extending therethrough, near 1ts concaved edgeS, through i which opening the tool head carrying rod 5 and the adjusting rod 6 extend. The tool head carrying rod 5 provided wlth a longi .tndlnally extending key Way 7 1n which keys 8 and 9'are seated. The keyS is carried by a metal plate 10 whichis attached to theupper surface 01 the body 1 by means of bolts 12 while the key 9 is carried by a lug 13 which is formed upon and depends from the plate 10, extending completely through the body 1.

The rod 5 is provided with a transversely extending recess 14 formed therein near its upper end, in which recess a portion of the periphery of a washer 15 is seated. The washer 15 is carried by the adjusting screw 6 for rotation therewith, and this adjusting screw engages threaded opening 16 which extends through the lug 13 as clearly shown in Fig. 3 of the drawing. A relatively large head 17 is formed upon the upper end of the adjusting screw 6 and it overhangs the upper end of the rod 5. The head 17 has its periphery knurled for facilitating the gripping thereof by the thumb and finger of the operator for rotating the feed screw to adjust the rod 5 vertically through the opening 4.

The rod 5 has a shoulder 17 formed thereon near its lower end and" the rod is reduced outwardly from the shoulder 17 and screw threaded to form the shank 18 which extends through the tool carrying head 19.

The tool carrying head 19 comprises a plate 20 the edges of which plate are curved as indicated at 21 in Fig. 5 of the drawing for fitting against the interior of a barrel. The plate 20 is provided with a recess 22 formed in its under surface, and with ribs 23 which extend along each side of the recess. A tool clamping plate 24 is inserted in the recess 22 and clamped against the cutting tools 25, 26, and 27 by a nut 28 whichis mounted upon the threaded shank 18.

The tools 26 and 27 are placed next to each other, upon the side of the shank 18 optool adapted to score the upper line of the plate attached to the upper surface of said groove in the barrel space while the cutting 'body board, a lug formed upon said plate edge of he other tool scores the'lower'lineof and extending through said opening, a tool 25 the groove. The tool 25 has a drag head 29 carrying rod extending through said lug, 5 formed upon its cutting end, the cutting end said rod provided with a longitudinal key 30 of which is square, for cutting out the way, keys formed upon said lug and located wood between the two scored lines made one at each side of the board and seated in by the points 28 of the tools 26 and 27, for said key way for preventing rotation of said 30 making the groove about the interior of the tool carrying rod, an 'adiustine' screw ad- 10 barrel in the staves thereof, upon the movejustably carried by said lug and passing ment of the croze about the barrel. through the opening in the board, means In'reducing the invention to practice, cerconnecting said adjusting screw and said tain minor features of construction, combirod for moving the rod iupon movement of 35 nation and arrangement of parts may necesthe adjusting screw, and a tool carrying 15 sitate alterations to which, the patentee is head carried'by'the lower end of said rod.
